DIABGAD - Trial to Preserve Insulin Secretion in Type 1 Diabetes Using GAD-Alum (Diamyd) in Combination With Vitamin D and Ibuprofen

Pilot Trial to Preserve Residual Insulin Secretion in Children and Adolescents With Recent Onset Type 1 Diabetes by Using GAD-antigen (Diamyd) Therapy in Combination With Vitamin D and Ibuprofen

The objectives of this study is to

• evaluate the safety and influence of treatment with GAD-Alum (Diamyd) combined with Vitamin D and Ibuprofen on preservation of residual insulin secretion in recently diagnosed Type 1 Diabetes
• evaluate how the above mentioned treatments influence the immune system of the subjects and interact with any viral infections
• evaluate the safety and influence of treatment with double dose of GAD-Alum (Diamyd) plus Vitamin D on the immune system, viral infections, and on preservation of residual insulin secretion in recently diagnosed Type 1 Diabetes

Main Inclusion Criteria:

• Male and female patients between 10 and 18 years of age
• Insulin dependent Type 1 Diabetes mellitus diagnosed within the previous 4 months at time of screening
• Fasting C-peptide level at time of screening above or equal to 0.12 nmol/L
• Elevated GAD65 antibodies (GADA) at time of screening

Main Exclusion Criteria:

• Treatment with immunosuppressants, continuous anti-inflammatory drug, Vitamin D or any anti-diabetic medications other than insulin
• A history of certain diseases or conditions (e.g. anemia, HIV, epilepsy, head trauma, neurological diseases or cerebrovascular accident, alcohol or drug abuse etc)

• Participation in other clinical trials with a new chemical entity within the previous 3 months
• Pregnancy or planned pregnancy within 1 year after the last GAD-Alum/placebo dose
